Evolutionary History Skyline

What should be displayed on the branches of an evolutionary tree?

• ancestors

• descendants

• common ancestor populations

A population of trout was stable for a long time. Then, their body structures changed to make them smaller. Why did this happen?

• Trout were meant to become smaller over evolutionary time.

• It is impossible to say without more information.

• Their environment must have changed.

• The crickets wanted to be louder.

The Sahara Desert has continued to be a stable environment for a long period of time. What would be the best way to describe the animals in their environment?

• Their body structure will become very different.

• Their body structures will continue to stay similar.

• Animals will always adapt, since evolution always happens.

• There is not enough information about the desert's climate.

Why would two different species share similar structures?

• Mutations randomly occur throughout generations.

• Both species share a common ancestor population.

Evolution is:

• the process of turning into a human

• a group of organisms of the same kind (in one or more populations) that do not reproduce with organisms from any other group

• the process by which species adapt to environmental changes over a very long time

• the process by which one population evolves into two or more different species
